GENERAL INFORMATION FOR HOUSE VENTILATION SYSTEMS:
1) Why changing the room air ?
A well designed ventilation system guarantees a comfortable feeling and
helps to keep the value of the building. The room air has to be changed for
hygienic reasons, and the humidity and pollution caused of people, as well as
various poisons - for example poisons of carpets, furniture, cleaning material
etc., has to be putted outside. Additional pollutions are also: Carbondioxyd,
Formaldehyd, Radon, Dust etc.
2) How to change the air ?
Because of well insulated buildings changing of the air will not be possible
automatically. For this reason a mechanical ventilation system is necessary,
just to provide changing of the air - independend of weather factors - according the needs of the residents. Very important is to keep the humidity and
the CO2 parts in the room air on a healthy level. An approximate value for
well room air is air-humidity of 40-55% rel. H. In case of humidity > 50 % mites will grow, in case of humidity > 60 % there will be mould on ceilings and
walls. The max. Carbondioxidvalue of the room air should not exceed approx. 1000 ppm. (The natural level of CO2 in outside air is approx. 330 up
to 450 ppm)
Seite KN-12

3) Characteristic of sufficient ventilation:
- The air remains fresh in all rooms
- Efficient and quick drying of bathroom and shower
- During heating period windows and doors in outside wall are always dry
- Also in the restroom air is always fresh
4) How much air will be changed ? For optimal air quality in a flat you
need an air exchange rate of approx. 0,4, that means that in an interval of
2,5 hours the airvolume will be changed. Basically the exchange rate has to
be adjusted to the requirements (New or reconstructed building - air exchange-rate 1, in bathrooms during shower also adjust higher values, etc.,)

Central Supply and Exhaust ventilation systems:
Such units guarantees a permanent supply and exhaust air for the whole
building. Normally fresh supply air will be leaded to the living rooms and
sleeping rooms. The exhaust air will be taken from the kitchen (without kitchen hood), bathroom and restroom.
The intake fo the air into the rooms will be effected in the upper wall or floor
and ceiling, through supply air valves. Through slots under the doors the air is
streaming from the living and sleeping rooms into the exhaust air area.
Because of the permanent air exchange bad air and poisons will be putted
outside. To provide best room air quality it is necessary to change the room
air volume within 1 or 2 hours (depends on number of persons).
Supply and Exhaust ventilation systems with heat recovery:
The warm extracted air of the living rooms transfers energy to the plates of the
heat exchanger, which is then absorbed by the outside air. The two airflows
are kept separate at all times within the heat exchanger (no odour bother).

2012-01

Techn. Änderungen vorbehalten - Subject to change

Possible ways of heat recovering:
- with plate heat exchanger
- with heat-pump
- with heat exchanger and heat-pump
Additional to the heat recovering with the unit a combination with a fresh air
fountain is possible (special designed duct installed deeper than the frost limit into the earth). Because of constant temperatures in earth, the intake air
will be warmed during winter months and cooled down during summer
months. Take care of the cleaning of this fresh air fountain because of possible mould during summer months.
Heating:
If you will not get the needed supply-air temperature with the heat-exchanger it is possible to heat with
- Electric heating battery or with
- Water heating battery (connection to the central heating system)

1. Function of the ventilation system: To guarantee best function pay
attention to correct planning and selection of the ventilation unit, as well as
to correct installation of duct system, silencers, air valves, etc.
2. Planning: for the best way of the air ducts and dividing of this system
into several parts. Establishment of the pressure loss for the concerning
part of the duct system, and calculation of the total pressure loss against
pressure loss graph.
3. Selection of the unit = Room volume x necessary air exchange rate =
needed power of the unit. The needed volume should be reached on step 3
or 5/6 (in case of digital devices). For this reason there is reserve power for
eventual needed short extreme ventilation (Cooking, Party, etc.)
4. Location of the cental unit: The unit should be located in warm area.
Surrounding temp. >+10°C, for example cellar, storage room, kitchen, etc.
For the condensate drain off there has to be installed a separate drain pipe.
Restrict air sound level - Prevention of structure born loss with vibration
damper.
5. Duct system for Supply and Extract air: Insulation of the ducts in nonheated areas. Pay attention to the shortest possible and a simple duct-system (small pressure loss). The minimum duct diameter is always 100-Connection to the unit always without reduction. Maximum air velocity in the
supply and extract duct 4m/s ! Ducts made of metal sheet steel (Noise,
Pressure loss, Hygienic reasons, etc.)
6. Duct system outdoor air and exhaust air: The max. possible distance

for the openings for the Outdoor air inlet and exhaust air (weather resistant louvre !). Outdoor air inlet on the shady side of the building in 3m height
- minimize the wind influence - Insulation of the Outdoor- and Exhaust air
ducts - maximum air velocity in the outdoor and exhaust air ducts 6m/s.
7. Selection and installation of the air outlets: The installation should be
effected at the nearest possible position to the source of the polluted air
(extract air), and not behind boxes, curtains, etc,. Pay attention to the best
air stream in the rooms (supply air) as well as to the noise level for supply
air outlets in case of to high air volume.
8. Duct silencer: Standard installation position direct behind the ventilation
unit, just to prevent telephonic sound between rooms, there has to be installated additional silencer. The attenuation should be >20 dB in case of
250 Hz.
9. Fire protection: In case of installation into detached houses there are
no special requirements for fire protection. For installation of the units into
public buildings or buildings which are used for commercial activities, pls
pay attention to the special laws for each country. (accessory: see fire
damper)
10. Roomdependend Fireplaces: In case of existing open fireplaces or
wood burning stoves, it is necessary to prevent underpressure in this
rooms, through ventilation with this units. The needed air for the burning of
these fire places has to be provided with a separate supply air duct (for the
dimension ask the producer of the stoves) direct from outdoors.

V …. Ceiling fans - For interchanging of the
air inside of entrance and waiting areas,
restaurants, offices, industrial and sports
areas. During the summer the fan provides
because of the airmovement a positive
aircooling. In the heating period the fan will
bring the warm air (big halls, tennis halls,
shopping centers,...) from the ceiling to the
floor and mix in this case the warm air from
the ceiling with the colder air. Because of this
the temperature in the floor area will be
increased, and therefore a reduction of
heating costs is the result. Our ceiling fans
are made of strong steel in a 3-impeller version with closed and maintenance free
60 watts motor. The device will be delivered
together with standard accessories following the situations on site a suitable and
strong fixing has to be done by the installer.
The motors are designed for speed
regulation by transformer and reversable.
As an option we provide also light kit and a
RC-remote controller.

Workmanship/Operation mode: made of galvanised sheet steel. Inletand outlet connections corresponds the standard diameter of spiralpipes
and flexible tubes.
Mounting: in any position possible – and depending on the installation direction “sucking“ or “pressing“ for Supply and Exhaust ventilation usable.
Structure-borne-noise: Flexible connectors between device and pipe
system is necessary
Noise level: To avoid noise pollution, mounting should be in a box-room or on
the loft.

TDE fans provides highest pressure level for transport of clean air. Because
of 50 % more efficiency energy saving of up to 30 % is guaranteed. Due to the
higher Air volume it is possible to reduce the size of the fans and you need
not so much space for installation.

TAILORED PRECISELY TO YOUR NEEDS
Different locations - different customers - different needs. The laminated
Aeromaster Cirrus concept allows you to select the unit height and width
according to your actual space requirements.
NEW CONCEPT: The unique casing design allowed us to abandon the traditional air handling unit sections and relationship between air handling unit
casing and internal components. The traditional concept of predefined
sections related to the particular built-in components is now consigned to the
past. The Cirrus concept is able to “enwrap” internal components with
minimum spacing using a casing of optimal length. The length dimensions of
each functional part (built-in assembly) of the air-handling unit are designed in
modular grid lengths equalling multiples of 102mm. These functional parts are
then integrated into assembly (transport) blocks in lengths equalling multiples
of 306mm (modular width of the lamina). This combination enables the
airhandling unit to be designed to specific length requirements.
OPTIMIZED COMPONENTS: The design of some built-in assemblies itself contributes to the optimized length of units. Combined filtration walls
are a good example of this. For example, fitting two filters into the
common frame will result in maximum reduction of the length.
ENERGYSAVING: A+ Energyefficiency, Highly efficient heat recovery
even above 80%, Highly efficient fans EFF1, Minimized pressure loss of
built-in assemblies. Excellent casing tightness L2, Eliminated thermal
bridges, Thermal insulation standard T3
CASING: Selfsupporting Panel, simple installation, high mechanical
strength and tightness of the casing contributes to energysavings. Very
good thermal insulation, excellent casing attenuation.
SIMPLE INSTALLATION AND FAST SERVICE: Optimized service
access doors enables easy entrance to the built-in assemblies, for
cleaning and service reasons.
NORMS: 2010/31/EU, 406/2000, EN15251, EN15240, EN15239,
EN13779, EN15242, EN15243, EN12599, EN15423, EN1886, EN13053,
VDI6022, VDI3803, DIN1946-4

The design of the fans is made with CAD Program. Internal
pressure loss are determined through the quantity of installed
components. External pressure loss following customers information
and the installed duct system.

Figures of maximum door heights mentioned are to be used as informative ones only
(for comparing with other air curtains manufacturer) and correspond to the reach of air
stream and drop of its mean air velocity to 2 m/s in an environment without draught. The
values correspond to inlet temperature of +18°C without filter.

Application: The direct airflow separates the clean indoor air from the conditions outdoors and avoids heat or cold loss as well as get in of insects
and dust through door opening.
They can be also used for efficient heating for the room. Even at opened
doors 80 % of the heating power is used for the room.

VCS 3 Finesse Standard colour white RAL 9010. Other RAL colours for
extra charge available. The delivery program has three widths 1,0 - 1,5 2,0 m. The airflow direction at the exhaust nozzle can be adjusted. The
units are equipped with operation thermostat, which regulates the exhaust
temperature to 45°C and a secure thermostat, which powers off the unit, if
the temperature in the device exceed 90°C. the heating battery is made of
stainless resistance heating elements. Protection class IP20.

correspond to inlet temp. of +18 ºC. The exhaust air is limited by the thermostat to +45 ºC.

VCS3-F-B FINESSE
VCS3 Finesse Standard painted RAL 9010. For extra charge - each RAL
colour available. The product range contains 4 sizes for five different door
heights, as well as widths of 1,0-2,5-2,0m, installation following a modular
system. The direction of the airflow on the exhaustnozzle is adjustable. The hotwater heat exchanger (Cu/Al) is designed for max. temperature of 100°C and
max. pressure of 1,6MPa.
In case of exhaust temperatures higher than 45-50°C the motors will stop
because of the overheating protection. After cooling down the motors will
start again. For this reason it is necessary to control the heating power of
the exchanger.

By throttling : setting of capillary thermostatic throttle valve on the heating
water inlet into a pit behind the heat exchanger. In case of combination of
air curtains one valve is to be used for each air curtain. By mixing of inlet
and outlet heating water by mixing valve (optimal regulation). The pump recovers the pressure losses of heater circuit and reacts quickly and exact to
the changes of measured temperature. Control of the output of the heat exchanger: A - in accordance with the outlet air temperature with channel temperature sensor mounted into a pit behind the heat exchanger. B - Following
the roomtemperature, if the sensor is placed on a suitable place in the room.
This possibility is suitable in case the air curtain is also used for heating.

Electric heating battery The operating mode depends to the connected
sensors and switches. A maximum of three fan speeds and two power
steps can be switched. About the functions see the following table.

Operating mode with outdoor temperature sensor and door switch
auto mode:
door closed: lowest air volume and power of heating
“ opened: air volume and power of heating increasing in dependence
to the outdoor temperature.
“
close: time delayed lowering of the fan speed (approx. 30 sec.)

Operating mode with outdoor temperature sensor, door switch and
room thermostat. Operating mode with this three controller components
guarantees optimal function and maximum energy saving.
Operating mode same as above but the room thermostat switches off the
unit after the temperature reaches the setted value.
Thermostat can be also used for water heating batteries, the heating power
will not be controlled but the unit will be switched off.

Application: The direct airflow separates the clean indoor air from the conditions outdoors and avoids heat or cold loss as well as get in of insects and
dust through door opening.
They can be also used for efficient heating for the room. Even at opened
doors 80 % of the heating power is used for the room.

VCV-Venesse air curtains are intended for vertical installation, for use in dry
indoor environments with ambient temp. from +5 °C up to +35 °C with max. 80
% rel. humidity and for transport of clean air without any pollution.
Version with electr. heater is equipped with one emergency thermostat
(115°C) and one limiting thermostat (50°C). Version with water heat
exchanger ist designed for max. 1,6 MPa and 100°C.

or chemical vapours-. Protection degree IP20, fans IP44, connecting boxes
IP54. The mounted heat exchanger are designed for 100°C and max.
pressure of 1,6 MPa. Stainless steel casing also available for e.g. car wash.
The combination of modules with and without heat exchanger is a so called
“active ventilation system”. In case of vertical mounting of modules - the lower
are planned with and the upper are planed without heat exchanger.
In case of horizontal installation it is possible to alternate the modules. The
composition of air curtains enables the user to solve the problem with the
heat source and to meet the requirements for the environment in the
protected room.

Antifreeze protection: In case of temperature decrease to the presetted
value the sensor PO (accessory or mounted) switches off the fans and
there is no further cooling of the heatexchanger. This mode of regulation
does not solve the control of the heat output..
Antifreeze protection and control of the heating output: In case of temperature decrease to the presetted value, the fans will stop while maximum
flow of heat media through the air curtain is ensured. This way of protection
requires installation of one sensor PO, which is put in case of vertical
mounting usually into the lower part of the module and in case of Horizontal
mounting in the middle. This sensor has to be connected to the mixing
valve SMU, to the regulation RJV and the channel sensor P12L1000.
